Abstract (en)
[origin: EP0529141A1] A switched-mode power supply which prevents input current surges and has sinusoidal current consumption as a result of suitable control of the switching elements which are used is intended to be improved in such a manner that the control of the switching elements which are used is simple. This is achieved in that a short-circuiting switch is pulsed in such a manner that it switches on and off, in each case simultaneously, as a function of the type of forward converter used for the voltage regulator, over the entire fluctuation range of an input voltage, which is produced from the input network AC voltage by rectification, using associated switching elements of the voltage regulator of the switched-mode power supply. <IMAGE>
